Inconclusive laboratory evidence of human immunodeficiency virus [HIV] (R75)
The ICD-10 code R75 is used to report cases where laboratory tests show inconclusive evidence of human immunodeficiency virus (HIV), meaning the results do not confirm a definitive diagnosis. This code is essential for identifying uncertain or preliminary HIV test findings.
R75 covers situations described as "human immunodeficiency virus p24 antigen detected" or when a patient is "reactive for both human immunodeficiency virus antibodies and p24 antigen" but without a clear confirmation of infection. These findings are characterized as abnormal laboratory results without a definitive diagnosis of HIV. This makes this ICD-10 code particularly useful for healthcare providers and medical coders when dealing with ambiguous HIV test results, supporting accurate documentation and appropriate follow-up testing.

Instructional Notations
Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Nonconclusive HIV-test finding in infants
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
